"Approximately" and "roughly"

Applying to College

<p>Is there a general rule of thumb when a school says "roughly" or "approximately", say, 300 words? Is anything from 275-325 acceptable? Or is the +/- bigger or smaller? Is under generally better than over? I don't want to make my essay to big and get it thrown out or something.</p>
